LMK00334 - Four-Output Clock Buffer and Level Translator

General Description

The LMK00334 device is a 4-output HCSL fanout buffer intended for high-frequency, low-jitter clock, data distribution, and level translation.

Key Features

  • 3:1 Input multiplexer.
  • Two universal inputs operate up to 400 MHz and accept LVPECL, LVDS, CML, SSTL, HSTL, HCSL, or single-ended clocks.
  • One crystal input accepts a 10- to 40-MHz crystal or single-ended clock.
  • Two banks with two differential outputs each.
  • HCSL, or Hi-Z (selectable).
  • Additive RMS phase jitter for PCIe Gen5 at 100 MHz:.
  • 15 fs RMS (typical).
  • High PSRR:.
  • 72 dBc at 156.25 MHz.
  • LVCMOS output wit.
